The lif'piidsin both reservoirs-10"und15'=lieve'at yiiiosplierie pressure on ftli'eirsui'l'iices, and the liowis controlled whollyY by gravity.

This lubreutoris not suhjectto clogging or is'dropped direct and iSindependent of'the condition oftheoil -due to differences inltemperature. 'Ihisidisplaeingliquid'is of 4uni- ;fim ifluidity greaterthan 'thutof l'the Joil A"und pingnozzle under all priictenl conditions.The outlet'vfor the oil through the tube 12, on

'lhe arrangement of funnel 20 anddrain-inlet 23 prevents the withdrawal of the liquid in the oil-cup 10below the inlet 23, and hence avoids getting oil into the tube i9.

Fig. .2 shows a-modilication in which I?, is j a water-supply pipelleading from a tank or reservdir or from a city water-supply system tosupply. the dropping device 16 and .in which there is a dropping device34 at the lower end of the overllow-tube l2 containedA in a sightchamber35. i

Fig. 3 shows a second modification adapted for the lliseeot a displacingliquid lighter than theoilsu`ch, for instancmpas kerosene. Inthisinstance the seeondaryjreservoir15 has an utlet into the top of theoilcup '10", and A the outlet-tube-12" is surrounded by a tube 36,havingan inlet near the' bottom ot' the oil-c`up and open at its upperendrto the atmoephere through a looseditting cap 14, so as to avoidaiphonieactioin.` ln this arrangement the displacing liquid ,leliiains`on 'top and forces the oil downwardly in the cup 10":unl-upthrough thetube 36 into the overIlow-tube l2".

lt will be understood that various changea in the detailed' construction'may be neuh, l without departing from the-spiritof theing vention. l 1l l l. in a lnbricator, an oil-reservoir open to the atmosphere andhaving an inlet in its top, z a gravity ovei'llow-outlct leading fromsaid reservoirja chamber Tor the reception 'of a l the atmosphere andhaving an inlet in its top` a gravity overflow-outlet leading from saidreservoir, a chamber for the reception of a liquid of a differentspecilic gravity from the oil, saidv chamber being also open totheatmosphere at its upper portion, and an outlet leading from said chamberto the inlet of said reservoir, and valve mechanism controlling saidoutlet.

3. In a lubricator, an oil-reservoir open to the atmosphere, aconduitleading to the lower part of the reservoir and, having its inletat thetop of the latter, a chamber supported upon said ireservoir andalso open to the atmosphere, an ontletleading from said chamber to theinlet of said conduit, and an adjustable d ropping device connected tosaidoutlet.

4. ln a lubricator, an oil-reservoir open to the atmosphere and havingan m'erilow-outlet, a water-elnunber having an outlet-conduit leading tothe lower partot'said reservoir, and

L drain having au inlet from said conduit loeated within thedischarge-mouth ofthe latter and above the plane of the latter.
